PYCNOIVIETER' SUPPORT AND DAM.

SPECIFICATION forming part of Letters Patent No. 532,1 20, dated January 8, 1895.

Application flled April 18, 1894. Serial No. 507,963. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM C. VAN VLIET, a citizen of the United States, and aresident of Brooklyn,in the county of Kings and State of New York, have invented a certain new and useful Pycnometer Support and Dam, of.

' pyonometer, and to the necessity, due to this cause, of washing and drying. and handling the pycnometer after it is filled, which gives time for evaporation and change in temperature, before the weight can be taken. By my invention these difficulties are largely obviated, for the reason that no overflow is permitted to come in contact with the body of the pycnometer, and only the stopper, and a small part of the neck of the pycnometer, need be washed and dried after filling, which can be speedily done and without taking the body of the pycnometer in the hands.

In the accompanying drawings to which reference is made, Figure 1 is a sectional elevation of my invention showing the pycnometer in place. Fig. 2 is a plan view of the same. Fig. 3 is a detailed view of the upper parts of the supports showing a modified means of adjusting the dam and Fig. 4 is a detailed view showing concaved bars for holding the dam in trough-like shape.

A representsa thin apron of soft india-rubher, or other suitable material, held at two ofin standards D, D, attached to a table or base E, so that the apron may be raised or lowered to suit pycnometers, or other bottles to be filled, of various heights, and so that the slant of the apron may be varied to facilitate the How according as to whether the liquid be viscous, or thin, and easy flowing. In the construction shown the bar B is attached to the upper end of the vertical rod F which telescopes into the standard D which latter is provided with a set screwf for holding it at any desired height. The bar B is journaled at its ends in upright bearing blocks 1) I) attached to a cross-piece B at the upper end of the verticalrod F which is telescoped into the standard D. This latter standard, like standard D, is provided with a set screw f for holding the rod F at any desired position in its vertical adjustment. The rod or roller B may be turned for drawing the apron A taut, and it is held from backward movement by a pawl and ratchet g as shown in Figs. 1 and 2. Instead of journaling the bar B to turn on its axis it may be made adjust- .able horizontally, to and from the bar B, by

and cause it to How down the apron and to support or hold the pycnometerlaterallyd ur 9 ing these operations. In this instancethe pycnometer is supported by a rest or stand H which, if desired, may be made vertically adjustable for different sized pycnometers, but this is not necessary, particularly if the apron be made vertically adjustable. The said rest H as here shown is telescoped in the stud H fixed at the centerof the base E and provided with a set screw '5 for retaining the rest at any desired position.

In some instances the bar B may be slightly concaved as shown in Fig. 4 to slightly elevate the edges of the apron to prevent liquid from overflowing the sides of the apron; and

the bar B is provided with a trough I to catch the liquid from the apron. This trough is held in place by arms k at the ends of the bar B and may be removed for emptying out its contents.

While I have described my invention as designed for filling-and holding pycnometers, I do not limit myself to such use as it may likewise be advantageously used in filling bottles with acids, poisons, liquid colors and for various other purposes.

Having thus described my invention, what. I claim as new, and desire to secure by Letters Patent, is

1. As a new article of manufacture, a pycnometer support and dam, comprisinga frame and supports therefor, and a flexible apertured apron to receive the neck of the pycnometer, attached at its edges to the said frame, substantiallyas and for the purposes described.

2. In a pycnometer support and dam, the combination of opposite adjustable bars, and

a central rest for the pycnometer, of an apertured apron held by said adjustable bars, above said rest substantially as described.

3. In a pycnometer support and darn an apertured apron, and opposite bars to which said apron is attached, in combination with a central rest for the pycnometer substantially as described.

4. In a pycnometer support and dam the base E and hollow standards D D attached to the base, in combination with the rods F, F, bars B, B, attached thereto, the apron A attached to said bars and a central rest for the pycnometer, substantially as described.

5. In a pycnometer support and dam the base E and hollow standards D D and H and the vertically adjustable rods F F and rest 11 in combination with the bar B, apron A and adjustable bar B, substantially as described.
